College Physics: A Strategic Approach Technology Update, Third Edition is accompanied by a significantly more robust MasteringPhysics before, during, and after class. New Dynamic Study Modules focused on fundamental math and physics concepts help students better prepare before class while new Prelecture Videos address common misconceptions students have when learning physics for the first time while reinforcing class preparation. Now, more than 200 new QR codes appear throughout the textbook, enabling students to use their smartphone or tablet to instantly watch interactive videos about relevant demonstrations, new Dynamic Figure Videos, problem solving strategies, and solutions explained by the authors. Newly Enhanced End-of-Chapter Questions offer students instructional support right when they need it, including wrong-answer specific feedback, links to the eText, and math remediation when completing homework assignments.
